ARP undercut head studs

[niscort]

I know its been mentioned a few times but nothing I have read comes to a conclusion, so Im hopeing for a final answer to

Do the 'undercut' 202-4702 arp ca studs fit?

Ive read they were the wrong thread, they are stronger, they were a stuffup and the wrong item from the factory...

As the part number is still advertised everywhere, have they fixed the issue?

I dont know. Just order the SR main stud kit. For some reason its cheaper too. 202-5402

there is a very cheap set of undercuts for sale atm, I would go the proven sr route if i was to order a set.

those are the ones I ordered and they had the wrong thread pitch go with the SR main stud kit.
